Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cableway (ropeway) as set forth in the preamble of claim 1.

(Problem to be Solved by the Invention) Cableways usually have cables which act as at least a means of traction for the vehicles connected to them, and whose loads change as a result of changes in temperature and, for example, as the number of passengers changes. However, there is also the problem of changing the length. This length change also acts as a distance change between adjacent vehicles, and since the cable has a certain circulation speed, the timing, and hence the predetermined time interval, between subsequent cabins is thereby disturbed.

It is therefore a challenge for the timing conveyor of a particular ropeway to recover the timing and correct the geometric spacing between adjacent vehicles when a vehicle passes a station.

However, if the phase position of an arriving vehicle changes due to a change in the length of the cable, this vehicle, which was still moved to the transfer zone by the conveyor in the disembarking zone, will stop in the transfer zone before being grabbed by the pusher dog of the timing conveyor. Sometimes. Therefore, the timing conveyor must be gripped by a pusher dog to accelerate the vehicle from a standstill, and at least the timing conveyor and its drive must be suitably and powerfully dimensioned.

However, a shift in the phase position of the vehicle may also occur when the vehicle enters the transfer section late and immediately after the shift timing conveyor. In this case, the pusher dog travels through the freeway section empty, and the remaining vehicle is pushed out of the freeway section only by a subsequent vehicle grabbed by another pusher dog. In such cases, the drive of the cableway must be interrupted in order to remove the vehicle from the circuit.

It is an object of the present invention to provide a structure that ensures the delivery of vehicles at a predetermined pusher dog of the timing conveyor while ensuring the conveyance of vehicles in the freeway zone, and at the same time, prevents collisions as much as possible.

(Means for solving the problem) This object is achieved by the features of the characteristic part of claim 1.

An advantageous configuration of the cableway according to the invention is obtained when the timing conveyor and the further conveyor have a common drive,
The drive device is also advantageously designed as a drive device for the cableway.

In this case, it is advantageous to arrange a continuously adjustable transmission between the common drive and both conveyors, which allows the circulation speed to be synchronized for adjusting the cable speed or the phase position of the vehicle.

In order to prevent problems resulting from extreme deviations in the phase position of individual vehicles, a means for monitoring the phase position based on the pusher dog of the timing conveyor is provided on the arrival side of the vehicle, before the mobilization section, and the fixed phase position is It is desirable to adjust at least the circulation speed of the timing conveyor by other means depending on the timing. In this case, the circulation speed regulating means can be designed, for example, as a continuously variable transmission.

(Function) Another conveyor transports the vehicle that has reached the free zone without regard to the phase position of the vehicle and keeps it in motion, so the circulation speed of the timing conveyor and the conveyance speed of the other conveyor are Since the required speed difference is small, the timing conveyor's pusher dog can pick up the vehicle virtually without collision.

The further conveyor is preferably configured such that it can transport vehicles throughout the transfer section. Therefore, the total length of the transfer section is basically long enough to guide one vehicle together with the pusher dog for the vehicle on the timing conveyor. This cableway can therefore be operated in such a way that joint guidance with the pusher dog is possible in the transfer section even if the vehicle is displaced by a predetermined phase in both directions.

The speed of the other conveyor, which is configured in a circular manner, is preferably in a predetermined relationship with the speed of the timing conveyor, and the circulation speed of the timing conveyor is selected to be faster than that of the other conveyor.

Therefore, a vehicle that has been moved through a transfer section by another conveyor is overtaken by a pusher dog attached to the timing conveyor, and is picked up by the pusher dog when overtaking.

(Embodiments) Hereinafter, exemplary embodiments of the cableway according to the present invention will be described in detail with reference to the accompanying drawings.

As is clear from FIG. 1, a rail 1 extending into a station, which is, for example, a station at the foot of a ropeway, supports a vehicle 2, and the vehicle is transported in the direction of arrow 3.

The U-shaped rail l provides a straight drop-off section 4 and a curved transfer section 5.
It is connected to the straight-line riding section 6 via.

Each vehicle 2 includes a passenger compartment 7, which is supported on the rails 1 via a running gear 8 connected to a suspension system 7a (FIG. 2). The vehicle is driven in the disembarkation section 4 and the pick-up section 6 via friction wheels 9 which are fixedly distributed along these sections in a known manner as illustrated and described in Swiss Patent Application No. 02468/86, for example. It will be done. At this time, the friction wheel 9 driven as not shown acts on the friction shoe 10 fixed to the suspension device 7a, and conveys the vehicle 2 in the direction of the arrow 3 via this.

The well-known timing conveyor 1 that ran along the freeway section 5
1 has one chain 12 and two pusher dogs 13 fixed to it. The pusher dogs 13 are secured to the chain 12 at a timing interval 14 apart from each other, which timing interval corresponds to the target distance between the vehicles 2 for a given travel speed, a given speed of the pusher timing conveyor 11.

In the case of this ropeway constructed as a single-track circulation cableway, the cableway truss/pulling cable 16 runs via a rope car 15. The rope wheel 15 has miter gears 17, 18.
19 and a shaft 20.21, it is drivingly connected to the shaft 22. The chain 12 of the timing conveyor 11 is connected to the shaft 22
It travels via a tin rocket 23 which is connected to the tin rocket 23 so as not to twist, and is driven by this.

According to the invention, a separate conveyor 24 is now attached to the swing section 5. In the illustrated embodiment, the further conveyor includes a circulation chain 26 which extends over the entire transfer section 5 and is provided with a bushing 25 as a chain attachment. A further drive sprocket 27 meshing with this chain 26 is connected to the shaft 22 in a non-twisting manner and its partial circle diameter is smaller (than that of the sprocket 23). Therefore, the circulation speed of the chain 12, 26 is in a fixed relationship determined by the diameter of the sprocket 2427, and the circulation speed of the other conveyor 24 (as compared to the timing conveyor 11) is slow.

The microphone gear 19 includes a continuously adjustable transmission 28 that allows the circulation speed of the timing conveyor 11 to be varied relative to the drive rotational speed of the rope sheave 15. The circulation speed of the timing conveyor 11 can therefore be made in a specific relationship to the actual cable speed.

During operation of this single-track circulation cableway, the vehicle 2 that has arrived at the disembarkation section 4 is transported by the friction wheel 9 toward the transfer section 5 at the disembarkation speed. As the vehicles enter the army zone 5, each
By grasping the suspension device 7a of the incoming vehicle 2, the individual bushers 25 are taken directly by another conveyor 24 without stopping. Typically, the circulation speed of the further conveyor is somewhat lower than the unloading speed, ie the speed at which the vehicles are fed into the transfer section 5 following the unloading section 4.

The vehicle marked with the symbol τ in FIG. 1 is already traveling in the direction of arrow 3 through a part of the march section 5 under the action of another conveyor 24. Meanwhile, the pusher dog 13 of the timing conveyor 11 is also entering this section. Normally the circulation speed is equal to the unloading speed of the vehicle 2 and therefore another conveyor 24
The speed is fast. As a result, the pusher dog 13 of the timing conveyor 11 approaches the vehicle τ under the action of another conveyor 24 while its conveying movement continues.

The vehicle G which is directly adjacent to the vehicle τ on the side of the riding section 6 in the transport direction and approaches the end of the floating section 5 is overtaken by the second pusher dog 13 of the timing conveyor 11, and this pusher dog 13 is connected to the suspension system of the vehicle G. 7a, and because the speed is fast, the engagement with the button 25, which had been effective until then, is disengaged. Having advanced from the cruising section, this vehicle τ is now delivered by the pusher dog 13 to the friction wheel 9 of the riding section in a predetermined phase position. This vehicle! and the vehicle i′ moving directly in front of it,
Since the transport speed of the riding section 6 is equal to the circulation speed of the tying conveyor 11, a timing distance 14 is established.

This timing distance of the vehicle 2 is clearly determined even if the deviation of the arriving vehicle from the predetermined phase position is relatively large.
This is achieved because the pusher dog 13 of the timing conveyor can grip the vehicle virtually over the entire transfer section.

When changing a given phase position connectively or briefly,
This can be done by changing the gear ratio of the transmission 28 during cableway operation.

Another conveyor is driven at a high speed than the timing conveyor, and normally the Zuck Ya Dog is driven by another conveyor).
It is also possible to overtake the transported vehicle in the free zone.

As a supplementary point, the present invention can be applied to chairlits as well.

Similarly, the boarding section and the disembarking section may be the loading section and unloading section of the freight cableway.

Finally, it should be noted that although in the illustrated embodiment the circulation speed of the timing conveyor is equal to the travel speed of the drop-off/pick-up section, the circulation speed may be much different. This is possible, for example, if the vehicle accelerates at the beginning of the leg and decelerates at the end of the leg, as described in Swiss patent application no. 05107/86.

(Effects of the Invention) As explained above, the present invention provides a system in which the transfer section 5 connects the disembarking section 4 with the boarding section 6 within the ropeway station, and the timing conveyor 11 circulates along the transfer section. 13 are arranged at a predetermined distance from each other,
A driving device for the circulation cable 16 drives this. A further circulation conveyor 24 extending along the transfer section 5 parallel to the timing conveyor 11 is equipped with a number of bushes 25 distributed over its length and whose circulation speed is somewhat slower than that of the timing conveyor 11. If a vehicle arrives at the freeway zone 5 too early with respect to the pusher dog 13 of the timing conveyor, this vehicle will be moved to one of the pushers 25 of another conveyor 24 until it is overtaken by the pusher dog 13 and taken over. Continued to be moved by one. The further conveyor therefore prevents the vehicle τ from stopping in the freeway section 5 even if the vehicle reaches the freeway section too late with respect to the pusher dog 13.

Due to the above-mentioned effects, the present invention can avoid obstacles caused by the following vehicle protruding into the preceding vehicle in the transfer section, and while ensuring the conveyance of vehicles in the transfer section, the predetermined pusher of the timing conveyor can be avoided. Vehicle delivery can be carried out reliably with the dog.
